Embodiment 1

[0022] The preparation process of the cementitious material for construction mortar of the present invention includes the following steps:

[0023] S1. Weigh the following raw materials: plant fiber, gypsum, ferrous sulfate, lime, sodium silicate, sodium fluorosilicate, glass fiber, sodium alginate, slag, silica fume powder, zeolite powder, nano clay, salt mud, calcium carbide slag , Glauber's salt, borax, wood chips;

[0024] S2. Put all the raw materials obtained in step S1 in the mixing drum and stir for 8-10 minutes to make the raw materials evenly mixed, and then add water to the mixing drum and stir evenly with the blade stirring head to obtain a fluid, colloidal coarse gelling material;

[0025] S3. Obtain the following raw materials: aluminum sulfate, sodium sulfate, sodium carbonate, citric acid, additives, stir aluminum sulfate, sodium sulfate, and sodium carbonate for 3-5 minutes to obtain a mixture, and add the mixture to the coarse gelation in step S2 In the material, a...

Embodiment 2

[0029] Based on Example 1, in step S1, the raw materials are weighed according to the following parts by weight: 20-38 parts of plant fiber, 10-15 parts of gypsum, 10-15 parts of ferrous sulfate, 10-30 parts of lime, 10-20 parts of silicic acid Sodium, 10-20 parts of sodium fluorosilicate, 10-35 parts of glass fiber, 10-15 parts of sodium alginate, 8-10 parts of slag, 8-15 parts of silica fume powder, 5-8 parts of zeolite powder, 3-5 parts Nano clay, 5-15 parts of salt mud, 3-10 parts of calcium carbide slag, 3-8 parts of Glauber's salt, 5-10 parts of borax, 8-25 parts of sawdust.

Embodiment 3

Abstract

The invention discloses a preparation process for a cementitious material for building mortar. The preparation process includes the following steps: weighing plant fibers, gypsum, ferrous sulfate, lime, sodium silicate, sodium fluorosilicate, glass fibers, sodium alginate, slag, silica fume powder, zeolite powder, nanoclay, salt mud, carbide slag, mirabilite, borax, and wood chip; obtaining a crude cementitious material of a flowing colloidal state; obtaining aluminum sulfate, sodium sulfate, sodium carbonate, citric acid and an auxiliary agent to obtain a target product; and sampling the target product and measuring the performance of the target product. According to the invention, through the interaction among the components, the plant fibers, vitrified beads and the like are added in the raw materials, which improves the heat insulation performance of the material.

Description

Technical field [0001] The invention relates to a preparation process, in particular to a preparation process of a cementitious material used for building mortar. Background technique [0002] Cementitious materials, also known as cementitious materials. Under the action of physics and chemistry, it can change from slurry to solid stone-like body, and can cement other materials to make composite solid material with certain mechanical strength. The development of cementitious materials has a long history. People use the earliest cementitious materials--clay to plaster simple buildings. The subsequent emergence of cement and other building materials have a great relationship with cementitious materials. Moreover, cementitious materials have some excellent properties and are widely used in daily life. With the development of cementitious materials science, cementitious materials and its products industry will surely take a new leap. [0003] Cement is often used as a cementing mat...
